It took a bit of work, but our site is now running the latest wordpress.  This means that anything that is available for wordpress (check out wordpress.org for plugins/themes) is available for our site.  This wasn’t the case in the past.  They were two separate tools, and the MU version (MU = multi-user) was always lagging behind the others.  This also meant that not all the themes and plugins worked.  Take a gander at what you might want there and let me know.  This would be for things like a better post-editor, better picture/video uploading, etc.
